Abstract:	The integration of advanced technologies is the only appropriate design philosophy for the development of an automated system for asset mapping. This paper presents the hardware and software components of a system developed for rail mapping in Australia. The system consists of a high precision kinematic global navigation satellite survey system (GNSS), a novel rapid, stereo video surveying system, dead reckoning (DR) sensors to improve the reliability of the position solution and orient the video imagery and a data management, analysis and reporting system with ArcViewTM GIS capabilities. A Kalman filter solution has been developed to integrate the survey measurements from the GNSS receiver and the DR sensors to provide regular updates of the vehicle’s position and attitude. This enables mapping of the railway trajectory and provides the orientation parameters for the video imagery. The stereo video survey system consists of three video cameras and recorders that are used to capture the location of point and linear infrastructure features. The video imagery is then digitised, stored on a server and linked to positioning data within the ArcViewTM GIS. The system architecture and algorithms developed will be presented.
